32x CD-RW Roundup Vol1

1. Introduction

The battle of
the Titans begin!

- Introduction

The 'need for speed' has been forcing manufacturers to produce faster and faster
CD-RW drives. Most users noticed a dramatic reduction of the writing time when
the first 4x, 12x, 16x models produced. The writing time was shortening even
further with the arrival of 24x recorders, while that was more or less the start
of the end of Zone-CLV writing technology. At the begging of 2002 year, the
32x recorders arrive and promises even shorten writing time.

After our first preview of the 32x writing proposal of Mitsumi (model CR-480ATE),
LiteOn and Freecom ship their first retail 32x recorders. Both drives have the
same writing speed (32x) but follow different implementations. We compare side
to side the three 32x recorders among with the faster 24x recorder (Yamaha 3200E).
How faster 32x recorders really are, compared to the 24x models? What about
the recording quality at the highest recording speed ever available? Continue
reading...

- LiteOn LTR-32123S

The
drive supports 32x writing (Z-CLV), 12x re-writing, 2MB Buffer and "SmartBurn"
as the main anti-buffer under run technology. The maximum reading speed of the
drive is 40x (CAV). The exact writing speeds are 8x, 12, 16x (CLV), 20x (16-20x),
24x (16-24x) and 32x (16-32x) (Z-CLV). The re-writing speeds are 4x, 8x, 10x
and 12x (CLV). The drive doesn't seem to support Mt. Rainier format as LiteOn
had promised in the press release (maybe this will come later with a newer firmware
update). What we have noticed is the addition of C2 error reporting which previous
the 24x model missed. Ending, the drive supports all known writing modes (DAO,
SAO, TAO and RAW).

means
Smart Monitoring & Adapting Recording Technology
for Burning. To get the best burning quality & reliability with smart
burning strategy such as media condition check, vari-speed burning, running
OPC & buffer under run free technology. The basic philosophy can be concluded
in the following picture:

As happened with the previous LTR-24102B series, the LTR-32123S drive contains
a predefined list of good quality media. When the CD is in that list, the drive
burns at a pre-specified speed with pre-defined writing strategy and you have
the maximum writing speed. When an unknown disc is inserted the drive will burn
it with specified speed, default strategy and running OPC at the same time.
Last, when a bad quality disc is inserted, LiteOn 24x will burn at vari-speed
in order to produce the maximum quality result. LiteOn continues to use Mediatek's
chipsets which are: ........ Last the "Smart-X" means Smart
Monitoring & Adjusting Read-speed Technology
-for- eXtraction. CD-DAE/VCD data extraction speed will increase or decrease
by host system demand (lower for playback or higher for copy) & media quality
condition.

- LiteOn's 32x writing speed

The LiteOn LTR-32123S supports 32x writing speed with the use of the Z-CLV
writing technology. LiteOn will use P-CAV for higher recording speeds (40x/48x).
Below is the Nero CD Speed writing graph which illustrates the use of Zone-CLV
writing technology:

The 32x writing speed range is divided into 4 zones: The drive starts writing
at 16x from lead-in till the 2mins, shifts up to 20x at 6mins, shifts up to
24x at 16mins and lastly shifts to 32x at 42mins and stays there until the end.
The average recording speed is 26.23X. From what we have noticed the
shift points are fixed in all cases. The LiteOn drive has the exact shift points
with Mitsumi's CR-480ATE but the Mitsumi 32x drive is slightly faster.

There is not any printed manual included - just an electronic PDF file. It's
nice to see at last a bulked 80min HS-RW media. We don't know yet if the LiteOn
LTR-32123S has 2 years of warranty (only in Europe) or not. Last as the package
says the drive is "XP" compatible which was confirmed from our test
results.

The front of the drive is exactly the same as with the 24102B series. The
drive includes the LiteOn's website url and the, the HS-RW logo and the drive's
features (32x12x40x). You will also find only one led, the eject button and
the headphone input jack/volume selector:

At the back of the drive we will find the usual connectors (IDE interface,
power), the jumpers for making the drive Master/Slave, the SPDIF output connector,
3 jumpers which are not used (factory reserved) and the analog/digital output
connectors.

- Installation

TThe
LiteOn LTR-32123S was installed as a Master in the secondary IDE BUS. The drive
worked in UDMA33 mode and after booting, identified itself as the "LITE-ON
LTR-32123S". We used both WinXP and WinME for the recording/reading tests.
Both OS's enabled DMA automatically.

The drive was a December 2001 model with firmware revision vXS05 installed.
We used a newer build of Nero (5.5.7.0), InCD (3.19), CloneCD (3.3.2.1) and
Padus DJ (3.50.826) for our recording tests.

If we use low quality media, the drive automatically lowers its recording
speed down to (16x/24x) before it starts writing. During our tests, the drive
lowered the maximum recording speed down to 16x when Mitsubishi Chemical's 80min
32x certified (prototype) media was used. As it seems the media code (97 34
23) wasn't yet added in supported media list. The drive lowered maximum recording
speed down to 24x ,when media based upon Plasmon/Maxell chemicals inserted.
There isn't any way to force drive writing at 32x with low quality media, which
many users might won't like, but its the only safe way to go :-)

2. Installation

- Freecom 32A

The
drive supports 32x writing (Z-CLV), 10x re-writing, 4MB Buffer and "BurnProof"
as the main anti-buffer underrun technology. The maximum reading speed of the
drive is 40x (CAV). The exact writing speeds are 4x, 8x, 12, 16x, 20x (CLV)
and 32x (20x-32x). The re-writing speeds are 4x, 8x and 10x. The drive doesn't
support Mt. Rainier format. The drive includes a C2 error reporting and supports
all known writing modes (DAO, SAO, TAO and RAW). Note that with the initial
firmware revision this is done at only 16x (CLV) speed.

The drive also supports "FlexSS-BP" which is the generic name for
"Flexible Speed" and "Flexible Strategy". The "FlexSS-BP"
works in 2 ways. When the drive judges that it can hardly trace the inserted
disc correctly -because a variation of media might include some serpentine tracks
and off centred discs- and that the placed disc cannot stand a high power laser
at high-speed recording, the drive selects the suitable recording speed for
the disc and continues the recording. Thus it monitors the physical condition
of the disc in real time during recording, and it flexibly switches recording
speeds in order to maintain the optimum recording condition. In addition, the
Flexible Strategy measures and evaluates the recording condition of a recorded
area at switching zones. Previously, the recording condition could not be checked
until the recording had been completed, but a Flexible Strategy drive can restart
the recording after the check of pit condition at the recording stop position
and optimise the recording parameters.

- Freecom's 32x writing speed

The Freecom 32A supports 32x writing speed with the use of the Z-CLV writing
technology. Below it's the Nero CD Speed writing graph that illustrates the
use of Zone-CLV writing technology:

The 32x writing speed range is divided in 3 zones: The drive starts writing
at 20x from the lead-in area till 12mins, shifts up to 24x at 16mins and lastly
shifts to 32x at 40mins and stays there until the end. The average recording
speed is 26.86X, which makes it the faster 32x recorder. Despite the
use of FlexSS-BP, the drive keeps the shifting points same in all cases. That
means, that even low quality media can be written up to 32x but with a major
cost. The readability of the written disc.

As our tests showed the FleSS-BP probably is not working correctly (or at
all) since we had C2 errors at the last minutes of each disc, especially at
the 20x (CLV) writing speed. That was noticed in almost all media (even with
Taiyo Yuden 24x certified). Similar problems were also noticed at the 32x writing
speed, which made us worried about the writing credibility of the drive. We
hope that a newer firmware revision will fix this...

- The package

The
package supplied was an "early" retail European version. This included:
the drive itself, an installation guide, a warranty registration form, IDE cable,
audio cable, a CD-R pen, 1 piece of Freecom 80min CD-R blank (actual manufacturer
Ritek) and mounting screws. The software supplied with the drive was Ez CD Creator
v5.1/DirectCD v5.1 and a diskette with updated drivers. There is an additional
CD with manuals for both Windows/MAC OS operating systems. The drive has 2 years
of warranty (only in Europe). The drive's price is estimated to be 175 Euro
plus Tax.

The front panel of the drive includes 2 leds (busy, write), the manual eject
hole, the headphone jack/volume control and the logos of "Freecom",
"BPRec" and the "High-Speed Recording":

At the back of the drive we will find the usual connectors (IDE interface,
power), the jumpers for making the drive Master/Slave, the SPDIF output connector
and the analog / digital output connectors. There are 3 jumpers at the left
of the back. The 2 jumpers on the left are not used (factory reserved), and
the third is being used for making the drive working at UDMA33 mode. If you
remove the third jumper, the drive works at PIO-Mode4 mode -suggested only for
any major in-compatibility:

- Installation

The
Freecom 32A was installed as a Master/Slave in the secondary IDE Bus. The drive
worked in UDMA33 mode with the default jumper setting and after booting, identified
itself as a "Generic Freecom32A".

We used only WinME for our recording/reading tests since under WinXP it was
impossible to force DMA for the drive. We don't know if this major problem has
anything to do with the Via's BustMaster drivers (4.37 installed) or firmware
needs upgrade to support WinXP.

The drive was a December 2001 model with firmware revision v2.40 installed.
We used Nero (5.5.7.0), DirectCD (5.1), CloneCD (3.3.2.1) and Padus DJ (3.50.826)
for the recording tests.

3. Data Tests

Data Tests

- SCSI Mechanic v3.0x results

The LiteOn LTD-32123S is the definite winner at the SCSI Mechanic tests,
since it has the highest performance of all competitor drives. The drive has
an average of 4623Kb/s when reading pressed CDs, while its' "Average Random
I/O" mark is high with 856Kb/s. The Mitsumi CR-480ATE comes second and
Freecom 32A comes third with 4464Kb/s "Average Sequential I/O" mark.
The drive's "Average Random I/O" mark is rather poor with only 659Kb/s
due to its high seek times, compared with the rest of the drives. Finally, the
Yamaha CRW3200E needs improvement since it comes last with 4459Kb/s.

At the Nero CD Speed test, the LiteOn 32x drive continues holding the first
place with 31.49X average reading speed. The Mitsumi CR-480ATE comes second
but now Yamaha CRW3200E comes third with 30.56X and Freecom 32A last with the
minimal 0.01X difference from the Yamaha 24x drive. The LiteOn 32x needs some
extra fine tuning in order to beat the PleXWriter PX-W2410A that holds the title
of the fastest CD-RW reader with 31.79X (with pressed CDs).

Things change when we look over the seek times. The Yamaha beats the competition
with only 84msecs, while Mitsumi and LiteOn have similar times (113msecs). The
Freecom 32A comes last with 126ms.

All drives improved their reading performance when CD-R media was used. The
LiteOn LTR-32123S gave an outstanding performance with 32.3X over passing the
competition. The Mitsumi CR-480ATE comes again second (31.45X), Freecom now
gets the third place (31.19X) and Yamaha CRW3200E comes last with only 30.56X.

For the RW tests we used the Mitsubishi Chemical/LiteOn Hs-RW media written
at 10x/12x speeds. The Mitsumi CR-480ATE is currently the faster drive when
HS-RW media was used with a 31.35X average reading speed. The Yamaha CRW3200E
comes close after with 31.13X, LiteOn LTR-32123S comes third and Freecom 32A
last with 24.93X:

4. CloneCD Tests

CloneCD Tests

- Procedure

We used CloneCD (v3.3.2.1) and 5 original CDs - Euro 2000 (SafeDisc 1), No
One Lives For Ever (SafeDisc 2), Rally Masters (LaserLock 1), Desperados (LaserLock
2) and V-Rally 2 Expert (SecuROM 2) - in order to test the reading time of the
drives. We also tested the reading performance with backups of the original
CDs, since the reading speed varies between original and backup media. For comparison
reasons we have added the results of the already tested Yamaha CRW3200E and
Mitsumi CR-480ATE. The following pictures show the drive(s) reading/writing
capabilities as CloneCD reports:

- PSX Pressed Media

For this test we used the PSX game 'NBA Jam Extreme' and we ripped the image
to the HD with CloneCD. The LiteOn LTR-32123S is again the faster reader with
only (?) 155secs. The Mitsumi CR-480ATE needs 265secs while the Freecom needs
273secs. The Yamaha CRW3200E comes last with 307 secs. All drives need improvements
since the PleXWriter PX-W2410A does the same task at only 54secs:

- SafeDisc 1/2 Results

The Mitsumi CR-480ATE performed very well with SafeDisc 1 CDs, outperforming
Plextor PX-W2410A but stays in the second place behind Yamaha CRW3200E. The
LiteOn LTR-32123S since it has hardware error correction; it manages to skip
bad sectors slow enough to get the third place since the Freecom 32A needs over
one hour to finish the task.

With SafeDisc2 protected CDs the LiteOn LTR-32123S has an average
reading performance, while the Mitsumi CR-480ATE keeps its performance high
enough to get the first place, at least with the original CD. The Freecom 32A
continues to hold the last place.

- LaserLock 1/2 Results

With LaserLock 1 protected CDs, the LiteOn LTR-32123S performed good enough
to get the first place with the original CD. The Mitsumi CR-480ATE performs
very well, especially with the backup CD while the Freecom 32A strongly holds
the last place.

The LiteOn LTR-32123S continues to perform well with an original LaserLock
2 protected disc. The Mitsumi CR-480ATE performs low with the original CD, but
makes a fast image with the backup.

- SecuROM Results

All tested drives can read SubChannel data from Data/Audio tracks. The Yamaha
3200E is the fastest reader, with the LiteOn LTR-32123S following at the second
place. The Mitsumi CR-480ATE comes third with a small difference from LiteOn
drive and finally Freecom 32A comes last.

5. DAE Tests

DAE Tests

- Test Method

We used CD DAE 99 v0.21 beta and EAC v0.9 prebeta 11 software
in order to check the DAE performance of the drive with various AudioCDs (both
pressed and CDR). The posted DAE results are the average of both applications,
but the CPU usage was only taken from CD DAE 99, since EAC occupies the system
a lot more. As a last note, we used the "BURST" reading mode of
EAC. We made a full CD Rip starting from the first to the last track of the
CD. The Average DAE reported speed along with the CPU Usage is displayed in
the test graphs.

- DAE features

We
used EAC v0.9 prebeta 11 to examine the Freecom 32A DAE features. As the program
reported, the drive doesn't "Caching" data, supports "Accurate
Stream" and doesn't include "C2" error info. The LiteOn LTR-32123S
does "Caching" data supports "Accurate Stream" and includes
"C2" error info. All 4 tested drives support up to 40x (CAV) DAE speed.

- Pressed AudioCD results

The Yamaha and Freecom 32A hold the fist place with 29X average DAE speed.
The LiteOn LTR-32123S has lower DAE speed since the drive delays to spin up
(spins up fully when it reaches the 3rd track) to full reading speed (CAV).
When the drive is rotating at full speed the numbers are higher (29.8X) but
for fair comparison we chose the lowest numbers. The Mitsumi CR-480ATE performance
wasn't good enough to compete the other drives and comes last with only 28.0X:

- CDR AudioCD results

The Yamaha CRW3200E holds the first place with 28.9X average DAE speed.
The Freecom 32A gets the second place with 28.4X and Mitsumi the third place
with 28.1X. The LiteOn LTR-32123S needs to reduce its spin-up time in order
to compete to the rest of the drives. In this test gets the last place with
27.31X:

- EAC Secure Extract Ripping mode

After many requests from numerous visitors we have added the
EAC's secure extract ripping mode results, which ensures maximum produced
WAV quality. Note that for each drive we used the build-in detection function:

- Advanced DAE Quality

All tested drives got a 100 score (best) in the Nero CD Speed Advanced DAE
test. The Freecom 32A drive's average reading speed was 29.20x and no errors
were produced. As the following picture shows, the drive can read CD-Text/SubChannel
Data:

The LiteOn LTR-32123S didn't perform so well and finished the Nero CD Speed
Advanced DAE test with only 26.09X average speed. No error was produced, while
this drive can read CD-Text/SubChannel Data too:

- Bad CDR Media results

Despite the fact that Nero CD Speed Advanced DAE test stretches
drive's mechanism to the max, we decided to do real life tests with a scratched
disc. The disc was dirty, and with some light scratches, enough in order cause
problems to most of the tested drives. We used CD DAE 99 software to rip the
whole disc (756539616 sectors) and the results were very interesting:

ThThe Mitsumi CR-480ATE recognizes both 90/99min AudioCDs without any problems.
The LiteOn/Freecom drives can recognize 90mins without any problems but failed
to read 99min CDs.

- Reading Protected AudioCDs

Since many latest AudioCDs are protected we decided to add such tests in our
reviews. For the test procedure we used 2 protected AudioCDs, which we tested
in both recognition and ripping (with CD DAE) processes:

Can read the contents of the disc (17
tracks Audio tracks + 2 Data tracks) but stops reading around 94%

Mitsumi CR-480ATE

As the test results showed, both AudioCD protections can prevent you from ripping
the CD contents if you are using the false reader. The Cactus Data Shield (CDS100)
disc couldn't be ripped from any drive since all tracks are showed as "Data"
and not as "Audio". Sony's KeyAudio is also effective with LiteOn
32x (drive ejects the CD out!) while the Freecom 32A can rip its contents up
to 94% (it then reports a reading error).

6. CDR Tests - Page 1

CDR Tests
- Page 1

- Procedure

We tested the LiteOn LTR-32123S/Freecom 32A with Nero v5.5.7.0, CloneCD v3.3.2.1
and Padus DJ v3.50.826 software. We used various media for performing our tests:
Mitsubishi Chemicals 74/80min 24x/32x certified, Mitsui 74min 24x certified,
Taiyo Yuden 74/80min 24x certified, Ricoh 74min 24x certified, Creation 74/80min
16x, Sanyo Digital 74min 16x and TDK/Ricoh/LiteOn's 74min HS-RW. The only 32x
certified media we had was from Mitsubishi Chemicals but also other manufactures
have 32x media ready. Note that the posted recording times below, are the
best we had from our test results. Different media can increase the time differences.

- Recording preferences

As
we explained before, the LiteOn drive supports all speeds above 8x. That includes
12x, 16x, 20x, 24x and of course 32x. Many users might be disappointed since
the drive doesn't offer lower recording speed than 8x! The drive includes the
"Smart-Burn" system in order to prevent buffer underruns but also
for checking the inserted media.

The
Freecom drive supports 4x, 8x, 12x, 16x, 20x and 32x recording speeds. The drive
makes a lot of noise at both 20x/32x recording speeds since reaches around 10.000rpm!
The attached FleSS-BP system seems to be needing improvement since most of our
written media contained C2 errors.

- Comparison

Before starting the recording tests, let's see how the drives are compared
in the writing/rotation speeds. The Freecom 32A is the faster drive for now
since it starts writing at 20x (CLV):

As we can see the Freecom 32A starts writing at higher writing speed than
the competitor drives and also shifts up to 32x earlier than both LiteOn/Mitsumi
drives. That boosts Freecom 32A average writing speed up to 26.86X when using
a 80min CD. The LiteOn/Mitsumi drives even have almost the same shifts points,
the Mitsumi CR-480ATE is faster by 0.11X:

Freecom 32A

The Freecom 32A starts writing at the highest -up to now- rotation speed (10.050rpm)
which is gradually reduced towards 16mins. The drive makes a lot of noise during
the writing process but it's necessary. The LiteOn/Mitsumi drives start rotating
at 8.000rpm and don't exceed 8500rpm anywhere during the writing process.

- 74min CD-R Tests

We created a "DataCD" job with data slightly more than
74mins (74:03:65). We burned the same job with all 4 CDR-W drives:

The Yamaha CRW3200E has the lower burning time at 16x (CLV) writing speed.
It needs exactly 310secs to end the task. The Mitsumi CR-480ATE follows, while
LiteOn LTR-32123S comes third with 315secs and Freecom last with 317secs.

Mitsumi CR-480ATE and Yamaha CRW3200E don't support 20x writing speed option.
However the other drives do, so we have a comparison chart :-)

As we can see the PleXWriter PX-W2410A holds the lower recording time with
259secs. The Freecom 32A comes second with 262secs. The LiteOn LTR-32123S and
AOpen CRW2440 are last with 266secs. This test shows that Freecom's 20x CLV
writing speed is not faster than Plextor's 16-20x Z-CLV implementation...

Let's see what is happening at the 24x writing speed. As we were expected
the Yamaha CRW3200E is the faster recorder at this category. The TEAC CD-W524E
holds the second place with 11secs time difference. The Mitsumi and LiteOn drives
come last with the exact burning time (239secs).

At last we hit the maximum recording speed of 32x. The Freecom 32A is the
faster recorder and its time difference varies from media to media. The best
result we had was 211secs (3:31mins). The Mitsumi CR-480ATE is slower by 7secs
and LiteOn LTR-32123S by 10secs.

7. CDR Tests - Page 2

With 80min CDs, the Yamaha CRW3200E holds the first place with 333secs. The
Freecom 32A comes second and the Mitsumi CR-480ATE third. The LiteOn comes last.

Again at the 20x writing speed, the Freecom 32A takes the second place. The
PleXWriter PX-W2410A come first with 278secs, the LiteOn LTR-32123S comes third
284secs and AOpen CRW2440 last with 285secs.

At the 24x writing speed, the Yamaha CRW3200E still holds the fist place
with 240secs. The TEAC CD-W524E follows with 247secs and the Mitsumi CR-480ATE
comes third with 253secs. The LiteOn LTR-32123S comes last with 255 secs.

With 80min CDs, the time differences between Freecom 32A and the competition
are increased. The Freecom 32A drive comes first with 220secs, the Mitsumi CR-480ATE
is 9secs slower than LiteOn LTR-32123S 11secs slower.

- Comparison of different writing technologies

The above graph shows the main differences between 24x Z-CLV, 24x P-CAV and
32x Z-CLV recording speeds. The Freecom 32A is the faster recorder at the maximum
speed of 32x and its time differences at 74min CDs are:

The time differences between various technologies points that 32x Z-CLV isn't
really a major breakthrough. Of course there would be users that always seek
for the faster and best recorder but...speed has its cost. In order to get maximum
speed you must use at least 32x certified CDs which not only would be hard to
find but possibly even higher priced than 16/24x media. Yamaha, with P-CAV,
shows the way to real increased speed towards rest manufacturers. Most next
generation recorders would use P-CAV in order to boost up further recording
speeds (up to 40x/48x).

- Zone-CLV visible zones

As most users have noticed, when using Zone-CLV recorders and specific media
(mostly based upon Cyanine) you can separate the recording zones with an eye
view. This effect happens due to different laser power and due to the reflection
of the light upon each zone. The visible separation of recording zones doesn't
affect the readability of the drive.

Below are 2 examples of written CDs with the Freecom 32A and LiteOn LTR-32123S:

The above pictures don't reflect the true image of the burned CDs due to
a limitation of the scanning process. However after the addition of the recording
zones you can separate each zone. From what our eyes have seen, the recording
zones between 24x and 32x for the Freecom 32A are harder to disguise from the
zones of the LiteOn LTR-32123S. You can easily see, after lead-in, the first
zone (20x CLV) but not rest (24x/32x). At the LiteOn LTR-32123S we have 4 zones
(16x/20x/24x/32x). With other media (mostly GOLD) the visibility of the zones
becomes almost impossible.

- Overburning Tests

Using Nero CD Speed, we saw that the LiteOn drive can overburn up to 99mins,
while Freecom 32A stops around 93mins.

- CD-Text Results

We created several AudioCDs with CD-Text enabled. Both Freecom/LiteOn drives
can read/write CD-Text AudioCDs without any problems.

- CloneCD Writing Tests

The
CloneCD v3.3.2.1 reports that both drives support the DAO-RAW feature. We performed
our usual tests and we confirmed that both drive support the DAO-RAW writing
mode at the following CD protections: SafeDisc 1.0, LaserLock 1/2 and SecuROM
2. Note that the Freecom 32A writes only at 16x when DAO-RAW writing mode is
used :(

- SD2 SupportFor the SD2 test we used the "No One Lives For Ever", "Max
Payne" and "Emperor Battle of Dune" game titles. We used the
LiteOn/Freecom drives both as reader/writer. The produced backup from Freecom
32A didn't work using the same or any drive we tested with. Therefore, the Freecom
32A cannot produce SD2 working backups. On the other hand, the produced backup
from LiteOn LTR-32123B did work in many drives we tested. Therefore the LiteOn
32x model can produce SD2 working backups.

Writing Quality Tests
for Freecom 32A

We used many media ,mostly 24x certified, and burned them at various recording
speeds with Freecom 32A. We used Nero 5.5.7.0 as the CDR software. The produced
CDs, were measured from DigitalDrives
and results are illustrated in the following tables:

At the maximum writing speed (32x) the Freecom drive has better behaviour
since the produced CDs contained lower error rate and not C2 errors. With some
media the drive produced many C1/C2 errors. New firmware updates can correct
this problem.

At the maximum writing speed (32x) the LiteOn LTR-32123S needs 3:41mins for
74min CD. For writing an 80min CD needs 3:52mins. The C1 error rate is higher
than 20/24x speeds but its natural.

RW Writing Tests

We used Nero 5.5.7.0 for writing CDs at the maximum RW speed for all the
tested drives. The LiteOn LTR-32123S support both 10x/12x writing speeds, while
the Freecom 32A supports 10x writing speed:

The Mitsumi CR-480ATE is currently the faster re-writer with 408secs for
writing a 74min HS-RW media. The LiteOn LTR-32123S needs 423 to finish the same
task. We did notice problems when Ricoh's HS-RW (4-10x) media was used for writing
at 12x writing speed. Even the project ended successfully, the media was un-readable.
When we used LiteOn's 4-12x HS-RW no problems were noticed. Last the Freecom
32A needs 486secs to complete the task.

- Packet Writing Tests

We used Ahead InCD v3.19/DirectCD v5.1 for the packet writing tests with
a Mitsubishi Chemicals HS-RW media. The formatted disc had 534mbs of free space.
We copied a 403 MB file (403.147 kbs) from a Hard Disk (on the same PC as the
writers) to the formatted RW media using Windows Explorer (we dragged and dropped)
and we completed the test twice to eliminate any possible time measurement faults
and user errors:

The Mitsumi CR-480ATE is still the faster writer at the packet writing mode
with 8.81X. The LiteOn LTR-32123S follows with 8.55X and Yamaha CRW3200E comes
third with 7.15X. The Freecom 32A comes last with 7.09X. The Yamaha CRW3200E
is the faster reader for packet writing formatted discs with 20.45X and LiteOn
LTR-32123S follows with 18.18X.

The Freecom 32A and LiteOn LTR-32123S come after Mitsumi CR-480ATE to clear
the clouds about the 32x recording speed. Many users expected that the 32x recorders
would offer a major performance upgrade over the 24x recorders. The truth is
that only Freecom 32A offers a noticeable time difference (20ses) against the
faster 24x recorder (Yamaha CRW3200E). That time difference with 74min CDs is
even smaller (14secs) which should make you start thinking if such small time
differences are important. The Freecom 32A may have proved the faster recorder
around, for now, but its produced written CDs contained not only C1 but also
C2 errors. This isn't acceptable since your written discs could end up un-readable
by several readers.

Getting more in details we must also note that: the drive's 20x CLV writing speed
is slower than 20 Z-CLV speed, lot of noise is produced when writing at 32x, CloneCD
users should look for a good reader since the drive's performance is very poor,
cannot backup SD2 CDs and we cannot guarantee that the drive is able to co-operate
with WinXP (at least we didn't manage to). On the bright side, the drive has very
good DAE performance and 2 years of warranty (applies only for Europe).

An alternative point of view

Maybe this last point should make you think again, about
buying (or not) a 32x Recorder especially in the case that you already
have one which can burn at a decent speed (let's say 20x/24x) and considering
an upgrade. Are 20 seconds less, really a difference? From our point of
view we wouldn't think so. If you MUST go for an upgrade then you might
want to look elsewhere; let's say the DVD-R / DVD-RW market. The speed is
not THAT impressive there either, but... you will be able to burn disks
that contain up to 4.7 GB of data, together with the 'cheap' CDR media you
are now using. Besides, the future of the Media recording certainly is NOT
lying on the CDR market anymore.

The LiteOn LTR-32123S supports not only "32x" recording speed but
also 12x re-writing speed, which makes it directly comparable to Mitsumi CR-480ATE.
The drive's writing performance was the lower among the 3 tested drive since
at almost all recording tests, the LiteOn drive came last (after Freecom 32A
and Mitsumi CR-480ATE). Firmware updates can improve drive's writing performance.
The drive's built-in detection system will prevent users from writing low quality
media at the 24x/32x speeds and the produced CDs will have very good writing
quality as our tests results have shown. CloneCD users will be satisfied with
both the ability to backup SD2 CDs and the fairly good reading performance.
Last you would be able to write 99min CDs but not sure if you could read them
afterwards.

It's quite interesting how good behaviour Mitsumi CR-480ATE had, even if
the drive was an engineering sample with a beta firmware. The Mitsumi CR-480ATE
has 2 unique features: It supports 16Mb Buffer and 'Mt. Rainier' format. Its
not the faster 32x recorder, but has very good writing quality. The drive's
weakest point ,against LiteOn LTR-32123S, is the lack of backup SD2 CDs...

Since both Freecom/LiteOn drives come from retail packages which most consumers
will buy shortly after Xmas, this roundup offers an overview off all positive/negative
points. Many other manufacturers are expected to ship 32x recorders during 2002
but as it seems, only the 40x/48x P-CAV recorders will be able to offer a real
performance difference from the 24x recorders.
